Encoding troubles UTF-8 in Eclipse/Rational Application Developer...

Uh, I never understood at all what is the reason for all these encoding types!
I had to do some modifications on a custom made JavaEE project which uses velocity template engine. I ended up having a lots of encoding problems.

Now I want to write sort of a step by step instruction how fix it.

Ok, so let's start.
Sooo, you have troubles with your spring/javaEE eclipse project. Several steps to take a look:


1) Check here: Window->Preferences->General->Workspace->Text file encoding - set to UTF-8
This setting will let even your new files to be encoded in UTF-8. It is usual cause of troubleshttp://www.blogger.com/img/blank.gif

2) under Window->Preferences search for encoding keyword and set everything you see to UTF-8 (this does not help too much, but sometimes is useful)

3) If your files are created outside eclipse project, check whether they are written/saved in UTF-8 coding. Notepad++ has a nice feature that is able to show you encoding of your file/text and also to convert from one encoding to another. TRY NOT USING UTF-8 WITH BOM (adds additional bytes to the beginning of the textual file so the editors can know this is UTF-8. Otherwise it causes  at the beginning of the file as soon as you get some encoding issues (like with ISO-8859-1 and CP1252)).

3.1) if you find this a bit problematic you can either use:
- Solution with Batch Convert to UTF-8 with Iconv and Sponge (under the moreutils package).
- Use the UTFcast Express Edition

4) Usually, Spring and velocity are nicely interconnected, and easily solve the issue with encodings, but if the velocity is directly used, one has to take care additionally to use the getTemplate function in the following way:
getTemplate(templateFile,"UTF-8");
Otherwise, it defaults to ISO-8859-1.

Timeline on Latex

One of nicer looking timeline graphs for Latex is by using the chronology package This is the example: \usepackage{chronology} ... \begin{chronology}[5]{1983}{2010}{3ex}{\textwidth} \event{1984}{one} \event[1985]{1986}{two} \event{\decimaldate{25}{12}{2001}}{three} \end{chronology} source .

Exporting Skype Chat/Skype Contacts to csv file using the shell script and sqlite3 (usually already installed on mac)

Edit: a very first draft version of Skype Exporter have been made and released. https://github.com/renesto/SkypeExportSwift/releases check it, and report any issues to renesto-at-gmail.com I heard there are not so many nice ways to get the chat history from skype, so I came across a page of one guy who shows a way to open the sql chat history database and delete all conversations. I thought to make something more from that idea (as delete chat history is now one of the options in skype) Create a file exportFromSkype.sh place either this text: sqlite3 -batch "$HOME/Library/Application Support/Skype/$1/main.db" < <EOF .mode csv .output $2.csv select * from Messages where dialog_partner = '$2'; .output stdout .exit EOF now make the script executable by running chmod +x exportFromSkype.sh now, when you want to export some chat history from certain person, you can do it by: sh exportFromSkype.sh your_skype_name your_friends_skype_name and i

trim() not supported by IE7 and IE8

Funny fact, trim function is not supported by IE7 and IE8. Ok, it is supported, but through jQuery trim function. So, when you have something like this: jQuery(...).attr().trim() , this trim() function stops having any relation to jQuery, as the attr() would return String type, which method would be then trim(). Since IE7 and IE8 do not support trim() method within String type, you should use instead jQuery.trim(jQuery(...).attr()) or if you don't wanna use jQuery (whyyyy?), you can simply implement the trim function youself. if(typeof String.prototype.trim !== 'function') { String.prototype.trim = function() { return this.replace(/^\s+|\s+$/g, ''); } } http://www.blogger.com/img/blank.gif source 1 source 2
